multiple tikv return inconsistent results when set config, the return message in sql layer should be more obvious

## Bug Report

Please answer these questions before submitting your issue. Thanks!

### 1. Minimal reproduce step (Required)

when set tikv configs, if multiple tikv return different results, like tikv-1 and tikv-3 return success, tikv-2 returns fail,
tidb should better return which tikv set failed, and which tikv set success.

### 2. What did you expect to see? (Required)
the fail message should be more obvious

### 3. What did you see instead (Required)
currently, sql layer will return success and put the fail message in warning, it is easily ignored by customer.

### 4. What is your TiDB version? (Required)
